Title: Analysing transitions in finite state machines
Inventor: LLOYD ALEXANDER HOWARD
IPC: G06K9/62
Filed: 1988-10-19
Abstract: In speech recognition words to be recognised may be represented by finite state machines and recognition is based on analysing transitions through the machines as an utterance occurs. One value which is required for each state of each machine in a timescale which is compatible with continuous speech recognition is minimum cumulative distance; that is the smallest value on reaching one of the states from a starting position, considering all possible paths. In the present invention a specially constructed Viterbi engine is provided for calculating cumulative distances at high speed. Latch circuits 50, 51, 52 holding pointers allow a RAM 41 to be read to provide, for a current machine state, both stored cumulative distances of states with transitions. A logic circuit comprising latch circuits 60 and 65 and an ALU 61 finds the cumulative distance for each path as far as the current state, selects the minimum using a latch circuit 56 and adds another penalty dependent on the current state. Thus a minimum cumulative distance is provided for storage and for a speech recognition decision making circuit. The process is repeatedly carried out for each state of each machine under the control of a controller 45. The total number of iterations of the engine in reaching each mimimum cumulative distance is also held in the RAM 41 and updated by the logic circuit. <IMAGE>

Title: Workpiece holding or positioning means
Inventor: BONIKOWSKI EDMUND JAN
IPC: A61B17/02
Filed: 1989-07-07
Abstract: A surgical retractor assembly comprises a rail (1) in the form of a ring which is adjustably supported by legs (4) above the patient from the operating table. A carriage (7) is mounted on the rail and carries a retractor (14). The retractor is mounted on one end of a first arm (13) the other end of which is pivoted to the upper end of a second arm (12) the lower end of which carries a ball (11) which is mounted in a socket (9) in the carriage. The ball can be locked by a manually operated wedge (32) which also causes a rod (47) extending up a bore in the second arm to lock the pivot between the first and second arms. Operation of the wedge also locks the carriage in position on the rail. Thus, the retractor can be positioned as desired and then a single simple operation causes the wedge to hold the retractor in this position. <IMAGE>

Title: A method of mixing and a mixing unit therefor
Inventor: CHAN SIMON YUK-LUN
IPC: B01F5/04
Filed: 1990-01-26
Abstract: A method of mixing first and second fluids, which are at different pressures, provides for the flow of said fluids along respective first and second flow paths which converge in a mixing zone. A mixing unit for carrying out the above method includes a housing 1 to which are attached valves (13, 14) which control the flow of said first and second fluids through first and second flow paths 24, 23 respectively. A nozzle 22 reduces the cross sectional area of the second flow path 23 through which the second flow passes to create in a mixing zone a jet or thrust of the second fluid which draws from the first flow path 24 a greater volume of fluid to improve throughput of the first flow and the mixing characteristics of the fluids. <IMAGE>

Title: Gas and smoke alarm systems
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: G08B17/10
Filed: 1990-04-26
Abstract: Existing multi-tube aspirated toxic gas and smoke alarm systems have either the ability to detect an occurrence quickly, but not to locate the source, or to locate the source but in the worst case only after an extended time interval with a probability of missing transient events. This invention, based on a novel rotary air selector valve 37, enables rapid detection of an event followed by rapid location of the source and also gives the ability to capture transient events and to distinguish between transient and continuing events. In operation, air from different zones is directed from tubes 22-28 through the valve to a common gas or smoke detector 32. Upon detection of gas or smoke, an alarm is energized and the valve is operated to successively direct air from each tube to the detector so as to enable location of the zone giving rise to the gas or smoke. <IMAGE>

Title: Photothermal deflection spectroscopy
Inventor: MASETTI ENRICO
IPC: G01N21/17
Filed: 1990-09-18
Abstract: An optoelectronic device for measuring the optical absorption of a beam of radiation (107) in thin layer materials (104) by photothermal deflection spectroscopy, comprises a laser source (100), an optical beam splitter (103) and a double position sensor (106). One of the beams (102) produced by the beam splitter passes through the region adjacent the zone heated by the beam (107). The refractive index of the medium in which the layer (104) is immersed is affected locally by the heating and causes beam (102) to be deflected across the sensor (106). Deflection of the other beam (101), which is not affected by the heating caused by beam (107), is used to compensate for vibration and for instability of the laser (100). <IMAGE>

Abstract: A process and apparatus for producing animal fodder. Selected dry ingredient materials are delivered from storage silos (12) and are prepared and mixed in a primary mixer (31) and then fat is added. Preset quantities of steam and molasses are mixed together and then added to the other ingredient materials in a controlled manner in a secondary mixer (35). This advantageously gives improved mixing and less trouble with plant running. Ideally also a selected quantity of water is sprayed onto granular ingredient materials when they are being conveyed from an intake hopper (10) to the storage silos (12) to counteract water loss during the process. <IMAGE>
